4. Given the following recursive function and it corresponding helper function that returns the sum of all the elements of an array that are located at even subscripts:
int sumEvenElements(int array[], int i){ if (i >= array.length)
return 0;
return array[i]+ sumEvenElements(array, i+2);
}
int sumEvenElements(int array[]){ return sumEvenElments(array,0)
}
Assume n is the length of the array. Find the initial condition and recurrence equation that expresses the execution time for the worst case of the recursive function and then solve that recurrence.
